Abstract
The disclosure relates 10 a device which is used to adjust the valve stroke of internal combustion engines and has an actuation element for the valve stem. The actuation element is actuated by the camshaft and has a receiving space for a pressure medium. The receiving space is fluidically connected to a reservoir space of an adjustment reservoir. The volume of the reservoir space can be adjusted by means of a reservoir piston. The reservoir piston is loaded toward the reservoir space with a force that is greater than the force applied by the pressure medium and that is less than the restoring force acting on the piston.
